AI Technical Summary

Benefits of technology

The solution effectively prevents residue defects and short circuits by ensuring proper patterning and insulation of the connection pattern, enhancing the reliability and manufacturing efficiency of OLED displays.

Problems solved by technology

Thus, as shown in FIG. 1, a short circuit defect is generated between the residue of the anode and layers stacked on the residue of the anode due to the residue problem of the anode pattern, thereby reducing the reliability of the OLED display.

first embodiment

[0059]FIG. 7 is a plan view illustrating a part of an OLED display according to a first embodiment of the invention, FIG. 8 is a plan view schematically illustrating a part of a line shown in FIG. 7, and FIG. 9 is a cross-sectional view taken along line I-I′ of FIG. 8.

[0060]Referring to FIGS. 7 and 8, a first initialization power line INIT1 extended from a display portion DP and a second initialization power line INIT2 connected to a pad portion 60 are disposed on a substrate 110. Further, a high potential power line VDD is disposed between the first initialization power line INIT1 and the second initialization power line INIT2 and is connected to the pad portion 60. A low potential power line GND is disposed on one side of the high potential power line VDD and is connected to the pad portion 60.

[0061]As shown, the first initialization power line INIT1 and the second initialization power line INIT2 are connected to each other through a connection pattern ALP positioned on the first ...

second embodiment

[0070]FIG. 12 is a plan view illustrating a part of a display device according to a second embodiment of the invention, FIG. 13 is a plan view schematically illustrating a part of a line shown in FIG. 12, FIG. 14 is a cross-sectional view taken along line II-II′ of FIG. 13, and FIG. 15 is a cross-sectional view illustrating another embodiment of FIG. 14. Structures and components identical or equivalent to those described in the first embodiment are designated with the same reference numerals, and a further description may be briefly made or may be entirely omitted in the second embodiment.

[0071]Referring to FIGS. 12 and 13, a first initialization power line INIT1 extended from a display portion DP and a second initialization power line INIT2 connected to a pad portion 60 are disposed on a substrate 110. A high potential power line VDD is disposed between the first initialization power line INIT1 and the second initialization power line INIT2 and is connected to the pad portion 60. ...

Abstract

A display device including a substrate, a display portion positioned on the substrate and a pad portion positioned outside the display portion, a jumping portion positioned between the display portion and the pad portion, at least two power lines positioned on the substrate, a connection pattern connecting the at least two power lines to each other in the jumping portion, and an insulating layer spaced apart from the connection pattern and surrounding the connection pattern to prevent residue defects and short circuit defects at the jumping portion.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from and the benefit under 35 U.S.C. § 119(a) of Korean Patent Application No. 10-2015-0123249, filed on Aug. 31, 2015, which is hereby incorporated by reference for all purposes as if fully set forth herein.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]The present disclosure relates to a display device, and more particularly, to a display device preventing a residue defect and a short circuit defect of lines.[0004]Description of the Related Art[0005]Various flat panel displays (FPDs) have replaced heavier and larger cathode ray tubes (CRTs). Examples of the flat panel display include a liquid crystal display (LCD), a field emission display (FED), a plasma display panel (PDP) and an organic light emitting diode (OLED) display.[0006]In more detail, an OLED display is a self-emission display device configured to emit light by exciting an organic compound. The OLED display does not require a ba...
